2. [80 points) A 50-22 lossless transmission line sends a sinusoidal signal to an antenna array of three antennas connected in parallel as shown below. The impedance at the input of each individual antenna is 75 22. The transmission line input is driven by a 1-GHz (109 Hz) RF transmitter that excites the line with V=120°Volts. Antenna 1 2. = 750 Transmission line 2-500 Load Antenna 2 2. = 750 2=-wavelengths away from load Antenna 3 2=750 z= (a) What is the load impedance of this line? (b) What is this line's voltage standing-wave ratio (VSWR)? (C) What is the phasor voltage that appears across the load? (d) What is the magnitude of the phasor voltage |(2)| that appears ” wavelength from the load towards the generator? (e) What is the largest magnitude of the phasor voltage that ever appears anywhere on the line and at what position z( in wavelength 2.) does it first appear closest to the load? (1) Sketch the standing wave pattern for both |ū(2) and (i(2)| over several periods from the load towards the generator. Clearly indicate where the maximums and minimums occur and what values they have (g) Suppose you connected an oscilloscope to the line at the location of a voltage standing-wave minimum and measured the voltage versus time. Sketch the oscilloscope trace that you'd see, labeling maximum and minimum values on the vertical axis. (h) What is the fraction of the net average power delivered to the load?
